我是Oracle SQL Developer的新手.我正在使用Oracle SQL Developer 3.0版. 我正在尝试使用以下查询来测试我的SP.

I am new to Oracle SQL Developer. I am using Oracle SQL Developer Version 3.0. I was trying to test my SP using the following query.

DECLARE
  type output_cursor is ref cursor;
  P_CURSOR output_cursor;
BEGIN
  P_CURSOR := NULL;
  myPackage.mySPTest (  P_NOTIFICATION_ID => 1975357,P_CURSOR => P_CURSOR) ;
END;

当我在Oracle SQL Developer中运行上述查询时，我收到一条消息匿名块已完成"，并且未显示任何结果.

When I ran the above query in my Oracle SQL Developer, I am getting a message 'anonymus block completed' and its not showing any result.

任何人都可以帮助我，如何查看结果.

Can anyone help me, how to see the result.

.

推荐答案

您可以使用SQL Developer中声明的绑定变量来保存并显示结果:

You can use a bind variable declared in SQL Developer to hold and show the results:

var r refcursor;
exec myPackage.mySPTest(P_NOTIFICATION_ID => 1975357, P_CURSOR => :r);
print r;

exec是匿名块的简写，因此等效于:

exec is shorthand for an anonymous block so this is equivalent to:

var r refcursor;
begin
    myPackage.mySPTest(P_NOTIFICATION_ID => 1975357, P_CURSOR => :r);
end;
/
print r;

除非P_CURSOR被声明为无用的东西，也许...

Unless P_CURSOR is declared as something unhelpful, maybe...
